I have checked the published research papers linked to Undenatured Type II Collagen, it looked like a promising treatment/cure for my wife’s arthritis. She has/had a hip problem and painful arthritis in her hands. Our main focus was on the hip, which after about seven weeks didn’t appear to be responding. She did notice at this time that her hands had very nearly totally recovered. There was no more pain on use and she could now shake hands again without the pain she previously had. There were still lumps on her thumb join that restricted some movement, but no pain. I think that with time the lumps will go away, so we will wait and watch.
